Abstract
A transmit and receive circuit for use in power line communication devices is provided. One embodiment of the circuit includes a receive channel with a first delay circuit coupled to a first switch having an open configuration and a closed configuration a first switch. The circuit also may include a transmit channel coupled to the receive channel at a node and including a second delay circuit coupled to a second switch having an open configuration and a closed configuration. When the switch of either channel is closed, the switch of the other channel is open. Data signals traversing either channel when that channel's switch is closed, are phase shifted approximately three hundred and sixty degrees and conducted back to the node.
